G E. BAUER, OF HAMMOND, INDIANA, ASSIGNOR'TQ AMERICAN STEEL F OUNDRIES, OF NEW YORK. N. Y., ACORPQRATION OF NEW JERSEY.-

" BRAKE-HEAD:

To all wit-(mm) may concern iBe at known that 1 .0mm. E. Bimini, a c tizen of the United States, residing at Hammond, in the qpunty of Lake and State to be'fitted 'upon the sleeve and which shall I be 'circumferen'tially complete at the point W of engagement with the sleeve this for the reason that many times a brake shoe becomes broken and the load is unequally applied to the face of the head. "If. the head is not complete circumferentially it is commonly he broken through the horizontal body portion thereof.

- A further object in the present construction is to provide a simple locking device.

which may be readily appliedand which if 2% broken or worn may be readily replaced at any repair point of a railroad. v

The invention will be more readily understood by reference to the accompanying drawings, wherein Figure 1 is a side elevation partly in section of'a brake head mounted on a sleeve and provided with my improved locking denice; Fig. 2is a section on the line 2-2 of Fig' 1; Fig.3 is a horizontal section on the line 3-3 of Fig. 1, the sleeve being omitted;

and Fig. 4 is a side elevation. of my novel locking device prior to application to the head.

Referring more particularly to thedrawings, it will be seen that the head 10 1s pr ovided with a transverse opening within which a sleeve 11 is fitted. It will be noted that the bearing portion of the head 18 C0111.

plete circumferentially, that is, is not broken 5@ at any point as in the sovcalled spht head.

This construction serves to obviate the possibility of breakage commonly occurring at or near the center of the head. The sleeve is provided with a circumferential recess 12-,

which recess registers with an opening 13 Specification of Letters .Tr'atent.

' formed in back of the head It will be 1110:. ders'tood .of course that the sleeve is rigidly head is rotatably mounted onthe sleeve. A fastenlng devic e 14 bent to the form shown 7 in Fig. 4: and provided with straight ends 15, 16 and with a bolt aperture 17 is adapted to be seated in the recess 12. in the sleeve, being applied through the opening 13 in the back ofthe head. The end 15'is allowed to remain straight prior to application 'to the head and to applythe 'samethe flat-end 15 is dr ven into place and'is sprung into the position shown in Fig. 1. Thereafter a bolt 18 is applied and the tightening nuts drawn up. The strap 14 is thereby rig-idly clamped to the sleeve and holds the head in adjusted position. If desired a key 19 may be inserted in front of the bolt 18 thereby preventing its accidental displacement, I

It will be noted that as long as the spring plate l-t is in place the head cannot beremoved from the sleeve in view of the' fact that the plate rests in the groove in the sleeve. This will serve as a locking means even though .the nuts should become loosened. p z I A construction such as described will be found exceedingly simple in manufacture and economical in maintenance. Obviously modifications may be made in the construction shown and such modifications as are within the scope, of my claims I consider within the spirit of my invention. I claim: 1. In a device of the class described, the combination of a peripherally recessed having an. opening registering with thereportion thereof curved and having straight ends, one end of which is adapted to be bent by being forced into a curved space in said head, and means for clamping the free end of said strap, whereby'to hold said headagainst rotation, substantially as described.

In a device of the class described, the combination of a sleeve, a head mounted thereon, a. space being left between said sleeve and head at a point in the periphery of the sleeve, a spring having a straight portion adapted to be forced into the curved space between said 'head and sleeve, and means for clamping the free end of said spring whereby to hold said head against secured to the end of a brake beam and. the

cess in the-sleeve, a spring strap having a sleeve, a head mountedthereon, said head ing straight ends, the ends of said plate being held by engagement with the head the curved portion of the plate bearing against said sleeve,' substantially as described.

4. In a device of the class described, the combination of a recessedsleeve, a head rothe lznaanea' tatably mounted thereon, said head being cast in a single piece and being provide with an opening in its back, a flat spring having straight end portions for engagement with said head and with a curved portion engaging said sleeve and bolt for forcing said spring against said sleeve, substantially as described.
